Joseph Witt commented on NIFI-2431:
-----------------------------------
code looks good. full clean build w/contrib check solid. Doing live testing
now.
> When a new node joins cluster, it can be elected Cluster Coordinator even if
> its flow is different than cluster's

> I have a 3 node cluster. I started 2 out of the three. I then removed the
> flow from the third node and started the third node, expecting it to inherit
> the flow from the cluster. However, when it started up, it was elected
> Cluster Coordinator before inheriting the flow. As a result, it determined
> that its flow (the empty flow) was correct. The other two nodes were then
> dropped from the cluster for having incompatible flows.
> The desired behavior is that the third node will not become Cluster
> Coordinator if a cluster already exists with an agreed-upon flow.
